Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8644B #9121744 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 8644B is a high-performance, low-noise signal generator capable of providing engineered and optimized waveforms covering a wide range of applications. It is used mostly in electro-optical engineering, automotive, defense, aerospace, and communications. This communications-grade signal generator delivers extremely low noise and low phase noise performance in a wide frequency range of 9 kHz to 2.6 GHz. The design of HP 8644B makes it an extremely reliable and accurate signal generator. It boasts a wide dynamic range, so it can produce high magnitude signals up to -134 dBm while still providing low levels as low as -200 dBm. It also includes a low-noise synthesizer and an RF output power range up to +14 dBm. A fast switching internal preamplifier improves tests, and additional output power is available with power levels up to +15 dBm with an external preamplifier. AGILENT 8644B includes a quick-change internal attenuator, which allows adjustment during testing. It also features an internal step attenuator and an attenuation accuracy of 0.5 dB. For external applications, the device offers an external attenuator (optional) which increases the attenuation accuracy to 0.25 dB. Its internal modulation system provides PM, FM, FSK, ASK, and PSK modulation. An external input allows external modulation sources to be used. Other modulation modes such as AM are also available when using external modulation sources. HEWLETT-PACKARD 8644B provides a range of markers that make it easier to analyze internal and external signals. It also incorporates a list mode that stores test results and allows for recurring tests. KEYSIGHT 8644B has an easy-to-read LCD display that offers a wide range of information about the device's performance, such as output power and frequency. It also features an embedded computer that permits a full range of operating features via a web interface. Users can also upload and store test files to the device, making it ideal for repeated test scenarios. 8644B has proven to be an ideal signal generator for a wide range of applications. Its wide range of features and high-level performance make it an ideal choice for testing and engineering purposes.
